- Migrate and save only settings which are enabled - Rename logger_http to logger_webhook and logger_http_audit to audit_webhook - No more pretty printing comments, comment is a key=value pair now. - Avoid quotes on values which do not have space in them - `state="on"` is implicit for all SetConfigKV unless specified explicitly as `state="off"` - Disabled IAM users should be disabled always
